Reverse Gear Day Mode The reverse mode is another important feature of this mirror. When the shift lever is placed in REVERSE (R), the mirror changes to the day mode. This gives you a bright image in the mirror as you back up. Compass Calibration Once the compass is calibrated, it does not need to be recalibrated as long as the mirror is left in your vehicle and the vehicle remains in the same geographical zone. To calibrate the compass: Mirror Settings OFF: This setting turns off the dayhight function and compass. The mirror will stay in the day mode. 1. Set the switch on the mirror control to C M . 2. Turn the vehicle ignition switch to ON. The letter C should be displayed in the mirror compass window. If not, hold the CAL switch (on the bottom of the mirror) for more than 10 seconds, and the letter C should appear. To hold i n the CAL switch, insert a paper clip into the small hole on the bottom of the mirror housing. The display will show a number first, but keep holding until the letter C appears. 3. For quick calibration, drive the vehicle in a 360-degree circle at less than 5 mph (8 km/h) until the display reads a compass direction. M: This turns on the dayhight portion of the mirror to automatically reduce glare. C/M: This setting turns on the compass in addition to the dayhight function. The letter or letters displayed in the top right corner of the mirror indicate the direction in which you are traveling. For normal calibration, drive the vehicle on your everyday routine, and the compass will eventually calibrate. 2-46
